Dust Storm over the Red Sea |
| Description |
A dust storm swept over the Red Sea on June 21, 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://www.aqua.nasa.gov/ ] satellite captured this image the same day. Dust obscured the satellite?s view of the Red Sea and the neighboring countries: Sudan, Eritrea, and Ethiopia on the west, and Saudi Arabia and Yemen on the East. Most of Earth?s dust storms arise in a few regions, including the Sahara and the Middle East. As desertification increases, dust storms are likely to follow. The Millennium Ecosystem Assessment has just released its Desertification Synthesis [ http://www.millenniumassessment.org/en/index.aspx ]. The report predicts that the planet?s dry regions will spread as the land surface responds to increased human pressure from poor crop and soil management and irrigation misuse.

Dust Storm over the Red Sea |
| Description |
The dust plume [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13665 ] that blew off the coast of Sudan on June 21, 2006, had petered out a day later. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this picture on June 22. In this image, the dust plume has dissipated and heads southward over the Red Sea toward the coasts of Eritrea and Yemen. Largely opaque the day before, the dust plume is now thin enough to show the ocean's surface.

Dust Storm over the Red Sea

Dust Storm over the Red Sea |
| Description |
In the summer months in the Northern Hemisphere, dust storms originating in the deserts around the Arabian Peninsula have a significant impact on the amount of solar radiation that reaches the surface. Winds sweep desert sands into the air and transport them eastward toward India and Asia with the seasonal monsoon. These airborne particles absorb and deflect incoming radiation and can produce a cooling effect as far away as North America. According to calculations performed by the NASA Goddard Institute for Space Studies (GISS), the terrain surrounding the southern portions of the Red Sea is one of the areas most dramatically cooled by the presence of summertime dust storms. That region is shown experiencing a dust storm in this true-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) acquired on July 11, 2002. The GISS model simulations indicate that between June and August, the temperatures would be as much as 2 degrees Celsius warmer than they are if it weren't for the dust in the air?a cooling equivalent to the passage of a rain cloud overhead. The image shows the African countries of Sudan (top left), Ethiopia (bottom left), with Eritrea nestled between them along the western coast of the Red Sea. Toward the right side of the image are Saudi Arabia (top) and Yemen (bottom) on the Arabian Peninsula. Overlooking the Red Sea, a long escarpment runs along the western edge of the Arabian Peninsula, and in this image appears to be blocking the full eastward expansion of the dust storm.

Jebel at Tair Eruption
| Title |
Jebel at Tair Eruption |
| Description |
Jebel at Tair, a small volcanic island in the Red Sea, erupted late in the day on September 30, 2007, causing several casualties and leaving a number of Yemeni soldiers missing, according to news reports. A Canadian Navy spokesman, who was in the area at the time, described a "giant light show" with spewing lava and an ash cloud reaching hundreds of meters into the air. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the diminutive volcanic island on October 1, 2007. The haze over the ocean likely results from the eruption, probably a combination of ash and vog—volcanic smog that arises from the mixture of sulfur dioxide, oxygen, and moisture. North of the island appears an area of potentially disturbed water, perhaps caused by ash in the water and/or hot lava leading to water heating and discoloration. Midway between Yemen and Eritrea, Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions. The island is also known as Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, and Jazirat at-Tair. According to The Sydney Morning Herald, Yemen has maintained a military base since 1996 on this volcanic island, which is only about 3 kilometers (1.9 miles) long. Yemen's oil minister stated that earthquakes, registering between 4 and 4.3 in magnitude struck the island on September 30 and likely triggered the eruption.

Locust Swarms in Africa and
…
| Title |
Locust Swarms in Africa and the Arabian Peninsula |
| Description |
Alone, the desert locust is nothing to worry about. It is a solitary creature that stays out of sight munching on plants. But when enough locusts are packed into a small area, they form aggressive swarms that migrate from place to place, consuming all vegetation in their path. The transformation from solitary insect to plaguing swarm happens when conditions force the locusts into close confinement. Along the shores of the Red Sea, the locusts' winter breeding area, swarms develop when rain falls on the sandy soil to initiate the hatching of locust eggs. If conditions are right—plenty of water and vegetation for food—in the locust breeding areas, a large number of the insects hatch and form swarms. In March 2007, locust swarms were sighted in the coastal plains along the Red Sea coast in Sudan, Eritrea, Yemen, and Saudi Arabia, said Food and Agriculture Organization (FAO) of the United Nations in its Desert Locust Bulletin. [ http://www.fao.org/ag/locusts/en/info/info/index.html ] The small swarms were breeding in the lush vegetation left by abundant winter rains. As the vegetation dries, the swarms are likely to move north and inland, warned the FAO. While locusts are not visible from space, the conditions that allow swarms to develop are easy to spot. This image, created from data collected by the SPOT satellite, shows vegetation conditions. Dark green areas indicate that vegetation was more thick and lush in March 2007 than the average March between 1999 and 2006. Brown areas show where vegetation was more sparse than average. Strips of dark green line the shores of the Red Sea in the same areas where locust swarms were spotted. The image also shows that plants are flourishing inland in Sudan, Eritrea, and Saudi Arabia, where the locusts could migrate. Because such satellite images map the conditions in which locust swarms develop, scientists use them as an early warning to identify areas that should be monitored for locust outbreaks.

Plume from Jebel at Tair |
| Description |
Jebel at Tair, a small volcanic island in the Red Sea, which had erupted [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14559 ] in late September 2007, released a volcanic plume on November 8, 2007. The Advanced Land Imager (ALI) [ http://eo1.gsfc.nasa.gov/Technology/ALIhome1.htm ] on NASA's EO-1 [ http://eo1.gsfc.nasa.gov/ ] captured this image the same day. In this image, volcanic plume appears as billowing puffs of white emanating from the summit. Evidence of earlier lava flows appears as dark stains on the volcano's slopes. Midway between Yemen and Eritrea, Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions. Jebel at Tair is known by multiple names and spellings. It has alternately been referred to as Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, Djebel Teyr, and Jibbel Tir.
